The Boston Red Sox released Portland Sea Dogs pitcher Kyle Jackson late Tuesday night. Jackson, 25, who first came to Portland for three games in the 2005 season, struggled this year. He had a 5-3 record, but a 6.47 ERA.

Jackson was moved to the starting rotation in hopes of kick-starting his career, but it did little good. In his last seven games (30 2/3 innings), Jackson allowed 29 earned runs.

Jackson was a 32nd round draft pick in 2001, out of Alvirine (NH) High and St. Petersburg (Fla.) College). His best year was 2006 (1.59 ERA in Class A, then 2.45 for Portland). Jackson was placed on the 40-man roster after that. He was taken off the 40-man at the end of the 2008 spring training.

Jackson's place in the Portland rotation has been taken by Ryne Lawson, 23, from lower Class A Greenville

In roster news in Boston, several media outlets are reporting that Mike Lowell (strained oblique) is going on the 15-day DL. Pitcher David Pauley from Pawtucket is replacing him - giving Boston an extra arm after Tuesday's slugfest.
